Jose Mourinho has already won the Europa League and EFL Cup at Man Utd

That’s according to Archie Knox who worked with the Old Trafford legend during his early years at the club.

Mourinho has already won the Europa League and EFL Cup during his stint in the United hot seat.

But Knox says Mourinho’s long-term impact on the club will be less pronounced than Ferguson’s.

Knox told Tribal Football: "The only thing you can say about him [Mourinho] and Sir Alex, they've both had phenomenal success.

"The difference in their success is that Fergie built the club from nothing up to winning all these titles and the Champions League.

“Jose Mourinho has already won the Europa League and EFL Cup at Man Utd”

"Mourinho, apart from Porto, has gone to big clubs and he has been able to recruit top players, but Alex built United from scratch, when there was no money to buy players.

"He continued with the youth policy and believed in the youth players coming through, there's the difference there.

"[It] was a long-term project and I think everybody at Manchester United recognised the amount of work that was put into bringing these lads through, and the club knew it was going to bring success sometime in the future and eventually it did, so the difference is Alex did that from scratch.

"Jose went into teams and obviously controlled the teams well and his style of football suited the club he was at, so both have had fantastic success, but I don't think Jose or any of the other [managers] apart from Arsene Wenger are going to be at a club for 27 years."

United will be looking to bounce back from last week’s shock 2-1 defeat against Huddersfield tomorrow.
